BACKGROUND OF THE NEW PLANT

The present invention includes a new and distinct cultivar of Rosa l.known by the varietal name ‘Tanabamar’.

The new plant was discovered in 1992 by the breeder in Ueterson, Germanyin a controlled breeding program. The female parent (Breeder Ref. No. RT8349) is an unpatented bi-colored yellow floribunda F1 numbered varietyfrom the breeder's private collection which is maintained proprietary bythe assignee. The male parent (Breeder Ref. No. RT 8342) is unpatentedand also a numbered variety from this collection and is a redgroundcover. The plant was discovered by the breeder on the Tanotaxplantation in Ueterson, Germany. The plant can be propagated asexuallyon Rosa canina rootstock by cuttings and has been so asexuallyreproduced in Uetersen, Germany.

The variety is distinguishable by its large flowers, its fragrance andcoloration, its shrub like appearance, and its resistance to diseases.Continued observations from the vegetative cuttings in Uetersen, Germanyhave confirmed that the distinguishing features of this new cultivarcome true, remain stable, and are retained through successivepropagations.
